Wireless Charging for Autonomous Devices: Safer and Efficient Solutions
Here’s PatSnap Eureka !
Summary
Problems
Existing autonomous lawn mowers require wired charging stations, which are cumbersome, pose tripping hazards, and can lead to poor contact and electricity leakage. Additionally, aligning wireless charging devices for optimal charging is challenging, especially for large devices like autonomous lawn mowers.
Innovation solutions
An autonomous moving device wireless charging system that includes a wireless charging station with a transmitting end and an autonomous moving device equipped with a receiving end, a charging battery, a wireless charging locating module, a driving module, and a control module. The system automatically aligns and docks the device for wireless charging, using modules like signal line search and charging signal detection to facilitate efficient charging.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If wired charging station is used, then charging function is provided, but tripping hazard and poor contact occur
Why choose this principle:
The patent extracts the exposed pole piece from the charging station design, burying it underground. Only the charging interface remains accessible at ground level, eliminating the tripping hazard while maintaining charging functionality. This is achieved by having the pole piece extend into the ground and connect to the charging interface beneath the ground surface.
Principle concept:
If wired charging station is used, then charging function is provided, but tripping hazard and poor contact occur
Why choose this principle:
The patent replaces the mechanical wired connection system with a wireless charging system. The wireless charging transmitting end is embedded in the ground, and the receiving end on the mobile device communicates and charges without physical contact, eliminating both tripping hazards and contact reliability issues.
